Female, 5'6", 115lbs, widest part of calf: 13". I know these are unisex so they would be a tad larger size-wise, but I wish there was a bit more in the way of compression. I don't think these would be the best option to prevent shin pain from progressing while running, but maybe I just need something smaller. Works well if I pull them up more and fold the top part over a bit, since they are smaller towards the bottom. Lover the material and the design is very minimal, which I appreciate.
